AI Technical Summary

Technical Problem

The existing high-density rheological tuning dampers can only work effectively in specific directions. The larger the angle between the vibration direction and the fluid communication tube, the smaller the energy consumption effect, resulting in poor effect in multi-directional vibration environments.

Method used

An omnidirectional high-density rheomorph tuning damper is designed. By setting up multiple partition plates distributed in an annular array in the housing, the inner part of the housing is cut into multiple fluid communication chambers, and electromagnetics are provided in the electromagnetic chamber. The body and iron solid particles use the magnetic field of the electromagnet and the movement of the solid particles to adjust the damping force.

Benefits of technology

A uniform and effective damping effect is achieved in a multi-directional vibration environment. Through the adjustment of the electromagnet and airflow regulating valve, the damping force can be flexibly adjusted, thereby improving the stability of the building under the action of multi-directional wind.

Description

Technical Field

[0001] The invention relates to the fields of damper design, and in particular to an omnidirectional high-density rheological body tuning damper and a building. Background Art

[0002] The applicant's research on "a high-density rheological body tuned damper and building" proposed a damping design of "high-density rheological body + ball + electromagnet". Its defect is that it can only meet the damping energy dissipation effect in any direction. To be more precise, the greater the angle between the vibration direction and the direction of the fluid connecting tube, the smaller the energy dissipation effect. For example, if the vibration direction differs from the direction of the fluid connecting tube by 90°, the damper will basically not work. In response to the above problems, the aforementioned application proposed "the concept of using two dampers in orthogonal directions" and "the concept of arranging several dampers in a ring". However, the above costs are relatively high.

[0012] Therein, the solid particles can be attracted by an electromagnet.

[0013] Furthermore, the flow-blocking holes are rounded and their edges are in a smooth curved shape, so that solid particles can roll freely between the flow-blocking holes.

[0035] Embodiment 1: An omnidirectional high-density rheological body tuned damper.

[0036] An omnidirectional high-density rheoform tuning damper comprises: a shell ②, a connecting chamber spacer ⑥, a high-density rheoform ④, solid particles ⑧, an electromagnet ⑩, and an airflow regulating valve ⑨.

[0037] The shell ② is provided with: a fluid communication chamber ① and an electromagnetic chamber ③.

[0038] Table 1 Structural design of an omnidirectional high-density rheological tuned damper

[0039]

[0040]

[0041] It should also be noted that the corners of the fluid communication chamber are in a smooth curve shape so that the liquid flows evenly and smoothly. Except for the openings on the upper parts of both sides of the fluid communication chamber connected to the airflow regulating valve, the other parts are sealed.

[0042] It should also be noted that: it also includes: an airflow regulating valve, which is located above the fluid communication chamber and communicates with the external air. The airflow regulating valve can be controlled by a computer to adjust the size of the air outlet, thereby changing the air pressure inside the fluid communication chamber during the movement of the high-density rheological body. By controlling the internal air pressure, the damping force of the fluid movement can be changed, thereby adjusting the damping ratio.

[0043] The omnidirectional high-density rheomorphic body tuned damper of the present application is installed on the top of the building. When subjected to strong wind, the building produces corresponding swings. At this time, the high-density rheomorphic body inside the omnidirectional high-density rheomorphic body tuned damper of the present application will shake due to its own inertia. In the fluid connecting chamber, the liquid levels of several connecting chambers in two directions of fluid movement alternately change up and down. In this process, the blocking of the fluid by the flow ring and the connecting chamber spacer, the friction between the fluid and the side wall, the movement of the solid particles (the potential energy change of the solid particles), and the air pressure above the fluid liquid surface can all produce a certain damping force, and the damping force can be adjusted by the electromagnet and the airflow regulating valve.

[0044] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the description of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
